It will follow a 5/8 inch garden hose in any pattern you create back toward the hose faucet. The shut-off ramp may be placed at any point along the hose to stop the sprinkler. The spray arms are adjustable and great for any diameter from 15 feet to 50 feet. Orbits traveling sprinkler covers up to 13,500 square feet traveling along 200 feet of hose (hose not included). In high gear the sprinkler travels approximately 37 feet per hour applying about ¼ inch of water. In low gear the sprinkler travels approximately 21 feet per hour applying about ½ inch of water. The rust-proof cast iron body and powder-coat paint allow for maximum stability and durability.
